Abstract

For more than a century, there has been interest in pulse wave velocity and pulse transit time as a possible metric for blood pressure and other cardiovascular parameters. The most common approach in noninvash:e measurement of these metries has been to measure the time delay between the QRS complex on the electrocardiograph and the detection of the finger photoplethysmograph. This paper introduces a new technique for measuring the brachial photoplethysmograph and argues that this forms a better timing reference than the QRS complex.
